It also clarified that the Boeing 737 aircraft had indeed returned to Mumbai due to "loss of cabin pressure" and the pilots have been taken off duty pending investigation, a Jet Airways spokesperson said in an official response.
Around 30 passengers on a Jet Airways Mumbai-Jaipur flight suffered ear and nose bleeds due to low cabin pressure during the flight's climb.
The Jet Airways said it has taken the concerned crew off-duty pending a probe into the incident.
A statement explaining what happened was released by Lalit Gupta from the Directorate General of Civil Aviation, which is responsible for commercial flight over India. As per initial information, few passengers had nose bleeding.
In January 2018, two pilots had been de-rostered by Jet Airways for fighting inside the London-bound Mumbai flight.
The airline said the flight's cockpit crew was taken off scheduled duties pending an investigation.
According to the NDTV, as soon as the pressure in the Jet Airways flight dropped, the oxygen mask came down and some passengers started to feel dizzy, and some complained about a headache.
All the passengers were treated at the Mumbai airport, but five of them were taken to Dr Balabhai Nanavati Hospital for a medical check where doctors said they suffered from mild conductive deafness, PTI reported. "No announcement on board to wear the oxygen mask", one person wrote, as he posted photos of himself inside the plane and on the tarmac after the aircraft landed. All guests were deplaned safely. "Out of 166 passengers on board, 30 are affected who have nose bleeding, few have ear bleeding and some are complaining headache", the official said. A video taken on flight shows that high amount of smoke was noticed inside the plane. "This is an unfortunate incident".
